I can confirm that there are three Disruptor towers with about 33K health, and that their death is what causes this vendor to spawn. A flare signal will go up from the Crystalforge and you will see a line of dialog indicating that the new NPC has shown up.

Wave 3 begins when the towers go down. At that point all new trash is 72 elite ethereals of three different types, and this is a raid level problem. I have killed the towers with 15-20 people in the raid; the problem is not the towers but the adds, of which there are a ton.

If you fail to beat the full 3 waves, the vendors will despawn when the Aether-Tech dies. Recommend that if you don't have sufficient strength to continue (and you don't if you have less than 25 doodz, it would appear), rush the vendor and get what you can before the Technician goes down. He can hold up a good 30 or so seconds being beat on by a few elites, more than enough time for you to make the buy.
